Did Senna’s title margins grow?
In the official final standings, they did. Senna beat McLaren teammate Alain Prost by three points in 1988, Ferrari’s Prost by seven in 1990, and Williams driver Nigel Mansell by 24 in 1991. The chart shows those recorded championship margins, not a normalized measure of driver superiority.
Official championship margins expanded from three to 24 points, across seasons with different scoring rules.

The context around each margin changes the story. In 1988, Senna scored 90 championship points to Prost’s 87 under the season’s best-11-of-16-results rule. The official race classifications list Senna with eight wins, Prost with seven, and Ferrari’s Gerhard Berger with the other victory. Senna’s title therefore came despite Prost earning more points across all finishes; the dropped-score calculation decided the championship.
Why was 1990 a different kind of fight?
Senna again won with McLaren, while Prost was now at Ferrari. Their points margin widened from three to seven, but it remained a close title battle between drivers in rival teams. Senna won six of the season’s 16 Grands Prix. The final standings give him 78 points to Prost’s 71; the values were determined under the contemporary dropped-score rules, so they should not be read as though every finish counted equally toward a modern table.
In 1991, the result was less tight on the final points sheet. Senna scored 96 to Mansell’s 72 and won seven times in 16 rounds. The points award for a win increased from nine to ten, and the best-of-season-results restriction was removed. That makes 1991’s 24-point gap larger both absolutely and under a different scoring structure. It does not mean that every performance dimension improved by the same proportion.
| Season | Senna | Runner-up | Margin | Grand Prix wins | Scoring context |
|---|---|---|---|---|---|
| 1988 | 90 pts | Prost, 87 | 3 pts | Senna 8; Prost 7 | Best 11 of 16; 9 points for a win |
| 1990 | 78 pts | Prost, 71 | 7 pts | Senna 6 | Dropped scores; 9 points for a win |
| 1991 | 96 pts | Mansell, 72 | 24 pts | Senna 7 | All results counted; 10 points for a win |
What do wins add to the points comparison?
Across these three title seasons, the runner-up and team context changed too: Prost was Senna’s McLaren teammate in 1988, his Ferrari rival in 1990, and Mansell drove the Williams in 1991. The margin therefore summarizes each season’s points table, but the competitive setting was not identical. It should be read with the winner counts and the season-specific scoring rules shown here.
The win counts give a separate view of how often Senna converted a race into first place: eight in 1988, six in 1990, seven in 1991. They don’t replace points, because non-winning finishes and the rules for counting results also mattered. Nor do they measure pace alone: reliability, qualifying, race incidents and the competitiveness of rivals all affect championship outcomes.
Senna’s record across these three campaigns is thus not one steady numerical pattern. The 1988 title was the narrowest and depended on a dropped-score rule; 1990 retained the same nine-point win value and also used discarded results; 1991 widened the margin while the scoring format changed.

Official final standings: 1988, 1990, and 1991. Official race records: 1988, 1990, and 1991. The 1988 and 1990 points use the seasons’ best-of-results regulations; the 1988 calculation counted each driver’s best 11 of 16 results. In 1991, all results counted and a win was worth 10 rather than 9 points. Margins equal Senna’s official final points minus the runner-up’s. Checked 2 October 2026.
